Description
Technical Field
The invention relates to the technical field of tool forging, in particular to a production method of a Damascus steel sword.
Background
The Damascus steel is characterized in that the surface of the steel has a numerous water wave-shaped pattern. These patterns are commonly referred to as damascene patterns. The steel has excellent strength and toughness and fracture resistance; the knife edge is sharp and unparalleled, and has long been considered as the king of weapons in the cold weapon age.
At present, the existing Damascus steels are mainly two types, namely, domestic Damascus steel and imported Damascus steel. The domestic Damascus steel is formed by folding and forging two stainless materials, wherein the forged patterns are formed naturally and are natural irregular lines. The melting point difficulty is high, the cracking probability is 5 times that of folding and forging of carbon steel, the hardness is about 53, the cost is high, the yield is low, and the patterns are single. The imported big horse is directly smelted from alloy powder steel, and various patterns are directly formed by machines. The texture is very regular, and the hardness can reach more than 60 but is easy to break through different treatments by a liquid quenching process.
For the related problems in the prior art, no solution has appeared at present.

cutting a pattern outline with the same size from top to bottom on the sword body according to a preset distance;
weighing maoeuve, straw iron and meteorite again according to the proportion of the second raw material, wherein the proportion of the second raw material is different from that of the first raw material;
folding and casting the maofen, the grass steel and the meteorite into patterns with the same size after cutting; and inserting the cast pattern into the remaining contour of the cut sword body, and returning the sword body to the furnace for heating and forging to obtain the finished product.
Wherein, the high-temperature forging of the hair iron, the grass steel and the siderite row to form the sword blank strip comprises the following steps: stirring the rough iron and the grass steel according to the proportion, forging the stirred material at high temperature, and forging the forged material into iron blocks; adding the siderite into the iron blocks according to the proportion, and after the siderite is added into the iron blocks, feeding the iron blocks again to forge into the sword blank.
Wherein, when the sword blank strip is repeatedly heated and bonded by transverse folding, the sword blank strip is bonded by S-shaped transverse folding.
Preferably, the preconfigured distance is 2-3 cm.
Preferably, the length of the sword body is 55-60 cm.
Preferably, the proportion of the first raw materials is as follows: according to the weight portion ratio of 1:1: 2.
Preferably, the second raw material ratio is as follows: according to the weight portion ratio of 1.5:1.5: 2.5.
Has the advantages that:
because the raw materials with different proportions are forged and combined twice, different patterns can be generated, the patterns are rich in variety, and the market requirements can be greatly met; meanwhile, the invention is directly formed by forging, thereby greatly reducing the production cost, improving the production efficiency and improving the smelting yield by 20 percent.
In addition, as the hair iron and the grass steel are subjected to fusion forging and then the meteorite is subjected to fusion forging, the trouble caused by different melting points of the principle can be effectively avoided, and the success rate of forging can be greatly improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic flow chart of a production method of a Damascus steel sword according to an embodiment of the invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
According to an embodiment of the invention, a production method of a Damascus steel sword is provided.
As shown in FIG. 1, the method for producing the Damascus steel sword according to the embodiment of the invention comprises the following steps: a production method of a Damascus steel sword comprises the following steps:
s101, weighing the hairy iron, the grass steel and the siderite according to the raw material proportion of 1:1:2 in parts by weight;
step S102, performing high-temperature forging on the hair iron, the grass steel and the siderite to form a sword blank bar;
step S103, repeatedly heating the sword blank strip, bonding the sword blank strip in an S-shaped transverse folding manner, and forging the sword blank strip until the length of the sword body is reached after the transverse folding is finished to form the sword body;
step S104, cutting a pattern outline with the same size from top to bottom on the sword body according to a preset distance of 2-3 cm;
step S105, weighing the maoeuve, the grass steel and the siderite again according to the raw material proportion of 1.5:1.5:2.5 in parts by weight;
step S106, folding and casting the mao iron, the grass steel and the siderite into patterns with the same size after cutting; and inserting the cast pattern into the remaining contour of the cut sword body, and returning the sword body to the furnace for heating and forging to obtain the finished product.
In practical application, when the hair iron, the grass steel and the siderite are forged at high temperature to form the sword blank bar, the hair iron and the grass steel can be stirred according to the proportion, and the stirrer is forged at high temperature to form an iron block; adding the siderite into the iron blocks according to the proportion, and after the siderite is added into the iron blocks, feeding the iron blocks again to forge into the sword blank. Firstly, two raw materials with the same melting point, namely maofei and grass steel, are forged and fused to an iron block, then merle raw materials with different melting points are added into the iron block, and at the moment, the special melting point of the merle is controlled. Therefore, the success rate can be effectively prevented from being influenced by different melting points, and when the method is adopted, the success rate is improved by over 50 percent. When S-shaped transverse folding and bonding are carried out, the pattern change is changed along with the S-shaped transverse folding and bonding; when the secondary proportioning blending is carried out, because the proportioning is different, the pattern at the moment has the patterns with different colors from the sword-shaped strips; after the furnace is returned, the pattern of the pattern and the pattern on the sword body form a sharp contrast.
In conclusion, by means of the technical scheme, the raw materials with different proportions are forged and combined twice, so that different patterns can be generated, the patterns are rich in variety, and the market requirements can be greatly met; meanwhile, the invention is directly formed by forging, thereby greatly reducing the production cost, improving the production efficiency and improving the smelting yield by 20 percent. In addition, as the hair iron and the grass steel are subjected to fusion forging and then the meteorite is subjected to fusion forging, the trouble caused by different melting points of the principle can be effectively avoided, and the success rate of forging can be greatly improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
